(01 156-114) This invention refers towindowsandmore par-' ticularly to wire screening for same, and has forits object to provide a screen using metal framing that will workeffectively: will permit the screen 5; or netting to be tightened whilethe frame is in place, will permit the insertion and removal of thescreen proper with facilityan d whichwill have means for connecting themoldings" used on the frame that will effectively connect into 'eachother and keep the frame substantially braced. Another object is'toprovide an arrangement for adjusting the position of thescree'n in awindow frame, and to provide a lock that will prevent the window screenfrom being opened in an unauthorized way. I

V 'Various inventions have been developed usingstructural shapes orrails that are cut to make a suitable frame, and to coact with sidemembers that guide and hold same, and a metal molding is provided forholding the screen or netting and give a finished appearance to thewhole screen.

In the drawings which illustrate by way of example, an embodiment ofthis invention:

Figure 1 is a front view of a movable screen for windows embodying thisinvention, and with par ts broken away to indicate the generalconstruction of the corners and center mullions.

Figure 2 is a front view of a stationary screen for windows of a specialtype.

Figure 3 is a horizontal section through the frame construction alongline 1616 of Figure 1.

Figure 4 is a vertical section through the frame construction along line1717 and showing the rubber bumper in bottom of frame, of Figure 1.

Figure 5 is a horizontal section through frame construction along line18-18 of Figure 2.

Figure 6 is a detail of the rack used in connection with the side railfor holding the window screen in adjusted and locked positions.

Figure 7 is a plan view of rack, shown mounted on side rail,

Figure 8 is an end view of the rack, shown mounted on side rail,

Figure 9 is a section of side rail, used in connection with the screen.

Similar reference characters refer to similar parts throughout thedrawings.

In-the construction shown, 1- represents a conventional window frame towhich is attached a side'rail 2 oraiumirium 'or other metal, dieformedin the shape indicated. This shape has a flat base 3 and a projectingshoulder 13 that has a 'quasi-wedgedlikesection, the" portion nearthebase being the' restricted portion. One side railmay have anadditional arrangement'of rack" teeth 4 to provide "'an arrangement foradjusting the'window height of screen "in open positions. The screenframe itself isprovided with a die-formed section rolled to the shapeindicated. Its main body portio'ri-fS-is flat and'one side 6 ischannelled to fit and slide over the shoulder' 13"of 'the'side member ofrail. "The other side of 5 is provided with "a lip 8 which is suitablyslanted, as well'as the rear of the channel portion' t'oprovide'atightening effect on the screen netting v'vhen"insertedinthe-frame. 1 I r The molding 31 is of flat material with its small edgesslanted to conform with the slanted portions of the main body portion ofthe frame, as indicated at 9 on both the parts. The molding may beprovided with ribs 10 or other suitable embossed or raised lines on itsupper surface to give it an attractive design. Suitable holes for screwsare provided at 11 in the molding. These holes align with holesscrew-threaded in the main body portion 5 at 12. The side rails areprovided with holes 23 for holding screws.

At the corners of the frame, the frame members are cut to a key-form 14to permit the same to be locked together and tightened against movementor shrinking action. This same type of lock is used for mullions 22 andother joints required in the frames and moldings for conventional orspecial windows.

The rack provided on the side rail 3 is provided with the teeth 4 whichare preferably constructed as indicated in the drawings, to permit thecatch on the lock to slide over same and then rest on their ledges 34with a slot 24 at the bottom for receiving the catch when desired tolock same. The lock is preferably of the type indicated and is attachedto the screen frame in a suitable manner. A rubber bumper 30 is providedin the bottom rail.

The side rails are provided only at the sides of the frame. In thespecial form of frame 25 shown in Figure 2 the metal of the frame isbent to suit thetype of window, and the joints 14 are locked in with thetype of headed lock joint referred to before. It is secured to thewindow frame. I

When the screens are mounted on the windows,

the frame engages with the side rails and may be raised, and held on therack in various positions of opening, or may be locked down when shut byallowing the catch of the lock to engage in the slot 24 the lock 19being provided on the inside or house side of the window. When it isdesired to replace the screen itself or netting 20, it is done so byremoving the molding, which is readily done by unscrewing the screwsfrom same and the frame. The molding, .-is taken: out,.;; being do;tached by lifting; The-netting isitliej'n removed. On replacing thenetting, the netting is inserted in the frame so that the side and topportions are inserted in the inside of the main body sections, Themolding is then inserted in the frame on top of the netting, andtightened down ,-Whi1 e.this is being done the slantingsides 9 of themolding and the main body portions;emtana un the rprisingin combinationa metal frame having secnetting taut. a, The mullions are provided inthe screen frames whereneeded, and have-J 'so-called, headedlock jointfor securing them substantially in place which also greatly strengthens;the, construction at1the- ,same time wi-thout detractingfrom itsappearance,
